We recommend all partners with 3CX Phone System servers which have the web server port exposed to the internet to secure their provisioning directory against brute force hacking attempts. This can be done easily as follows:

1. If using 3CX Phone System v9 with the Abyss web server – upgrade to service pack 4. This will automatically activate the anti hacking feature on Abyss.
